Changing WAN Port Parameters
The ProxyServer is designed to provide the flexibility needed to meet today's application needs. The
WAN Setup dialog provides the controls for WAN configuration. Each WAN port can be configured
independently of the others, or they can be combined depending on your application needs. Beyond
the basic controls offered in the Mode and Connection Method groups (described in detail in your
on-line Help system) the WAN Setup menu includes many advanced features.
The sections that follow detail the function of those features and provide examples of how they can
be put to use. In addition, where relevant, they detail how certain features affect other dialogs in the
Proxy software.
Link Usage Control Group
Note: The Link Usage Control Group is not supported when using MLPPP.
The Link Usage Control group allows you to control the conditions and parameters of the traffic on
the three WAN ports. Using the Enable and Idle Time features, you can cause the ProxyServer to
drop the connection on the selected WAN port after a specified duration without activity (as defined in
the Idle Time field). The default setting is enabled (checked) with an idle time of 10 minutes. If you do
not wish to use this option, click to disable (uncheck) it.
The Bring up port if more than group allows you to configure WAN ports 2 and 3 to become active
based on the level of traffic detected on the WAN links. You can configure the Proxy to bring up an
additional WAN port(s) based on the number of active connections or on the number of active IP
host machines. This group does not apply to WAN 1 and is therefore inactive (grayed out) when the
WAN tab selected.
The ProxyServer can be configured to limit certain workstations, based on IP addresses, to a
selected port using the Hosts restricted only to this port group. The first of the two fields in this
group defines the IP address of the workstation to be restricted. To add a new restriction, enter a
valid IP address of a workstation in this field and click Add. The new entry will appear in the list of
restrictions below. This group is not applicable to WAN 1 and is therefore inactive (grayed out) when
the WAN 1 tab is selected.
Beyond the actual WAN port controls, the ProxyServer includes features that enhance WAN
communications and maximize bandwidth and efficiency. The next three sections, Dynamic
Bandwidth Allocation, MLPPP, and Port Type discuss a variety of configuration options that make use
of these features.
